Sun-2/100U The Next Chapter

Hi again, Thanks for all the help with getting the thing booted, I managed to get the miniroot installed on xy0 (an aging Fujitsu M2322K on a Xylogics 450(451?) controller), and it boots quite happily off the miniroot into single user mode, the SunOS install program is quite advanced for 1986, and very easy to use! Just select the packages and put the tapes in when asked. Along the way i've noticed that one of my memory cards seems to be faulty, it currently has 7mb of ram (4mb + 1mb + 1mb +1mb), after numerous "Protection Bus Faults" I removed all but the 4mb card, and all is fine, i was able to up it to 6 and isolate the faulty card. I'll probably end up replacing most of the 4164 chips on that board, i think I have a box full of them somewhere :) The only problem I seem to be having is that, the first time I installed SunOS, when it goes to boot multiuser, it stops at "Using 100 buffers containing xxxxx bytes of memory" then appears to write continously to the HDD, (I verified this by clicking the WP switch on, and it dumped errors everywhere). it's not the rc files, i'll have a go at reinstalling SunOS again and see. There appears to be another problem, I don't have the manufacturers bad block data for the drive, and as such when i reformatted the drive it has no bad block info.... Now I did try "scan" in the diags to rebuild the bad block table, at which point it filled the bad block table and declared the drive unusable. I am slightly dubious of this, as the format/verify then failed where it had worked previously. Resetting the drive returned things to a sane state, and the format/verify completed correctly... any ideas? On the up side, the Tapemaster 1/2" tape and the ethernet interface is working, when it does finally work it'll be plugged into the university LAN....should make an interesting curiosity :) Cheers Karl ------------------------------------------------------------------------------ Karl Maftoum Computer Engineering student at the University of Canberra, Australia Email: k.maftoum(a)student.canberra.edu.au
